Re: Sony AIT-1 tape backup

[Brendan Simon <BrendanSimon@fastmail.fm>]

More info,
   # mt erase

   # mt seek
   /dev/tape: Input/output error

   # mt status
   SCSI 2 tape drive:
   File number=-1, block number=-1, partition=0.
   Tape block size 512 bytes.  Density code 0x30 (AIT-1 or MLR3).
   Soft error count since last status=0
   General status bits on (1010000):
      ONLINE IM_REP_EN

Any ideas why I get I/O errors???

TIA, Brendan Simon.
